' Specification of Letters Patent. Application filed February 24, 1312. Serial No. 679,718.

Patented Dec.-3, 1912.

Be it known that I, HEN-BY Beer, of Worthington, Nobles county, Minnesota, have invented certain new and useful Improvements in Corn-Gathering Machines, of

which the following is a specification.

The object of my invention is to improve the machine covered by'Patent No: 815,220, issued to me-March 13,;1906.

The invention consists generally in a snapping roll rotating at a comparatively high rate of speed, and a second roll rotating .in the same direction at a slower speed.

Further the invention consists in various constructions and combinations, all as hereinafter described and particularly pointed In the accompanying drawings forming part of this specification, Figure 1 is a'plan.

view of the lower portion of a machine embodying my invention, Fig. 2 is a longitudinal vertical section on the line H of Fig. 1, looking in the direction of the arrow, Fig. 3 is a similar View, looking toward the opposite side of the machine, on the line yy of Fig. 1, Fig. 4 is a detail plan view of the rolls, the snapping. roll being removed to expose the roll beneath it, Fig. 5 is a transverse sectional view, illustrating the operation of the rolls, Fig. 6 is a vdetail sectional view, showing the means operating in connection with the gathering devices for engaging ears whichmay be low down on the stalk or close to the 'ground- In the drawing, 2 represents the frame of the-machine, having a traction wheel 3 and a carrying wheel 4.

5 is a transverse shaft, driven bya belt 6 from the traction wheel, as usual in machines of this type. The operation of this shaft is controlled by a clutch 7.

8 represents a comparatively large rotating, smooth-surfaced roll-,jou'rnaled in stationary bearings and. having a shaft 9 provided with a beveled pinion 10 which meshes with a beveled gear .11 on the shaft 5. A gear 12 is secured on the shaft 9. andmeshes with apinion 13 on a shaft 14 of movable bearings 16 and is yieldingly held toward the roll 8 by springs 17. The tension of these springs is regulated by adjusting screws 18. The roll 15 is provided with a longitudinal, spirally arranged rib 19, extending from end to end of .the roll and between the convolutions of the spiral I prefer of the roll 27 to provide toothed blades or webs 20, also extending lengthwise of the roll. This roll is also preferably tapered from its upper toward its lower end, its driving connection with the shaft 9' operating to rotate the roll in the opposite direction from the movement of the roll8. A shaft 21 is journaled ,in the frame of the machine, parallel with E-the shaft 5, and has a pinion 22 secured :thereon meshing with a comparatively large gear 23 on the shaft 5. A beveled gear 24 is mounted on the shaft 21 and meshes with :a beveled pinion 25,0n the shaft 26 of a roll '27 that is journaled in adjustable bearings jabove the roll 15. This roll has a series of ribs,28 formed thereon by means of longitudinal recesses and is driven in the same directionas the roll 8 but at a greater speed.

The bearings of the roll 27 are connected to rods 27 extending transversely of the machine and slidable in guides 27" and having threaded ends to receive the" interiorly threaded -hubs of sprocket wheels 28'. These sprocket wheels are held against movement transversely ofthe machine by brackets 29" and are free to revolve and ,IIIOVG the rods lengthwise, arid adjust the roll 27 toward or from the roll "8 to increase or decrease the distance between these rolls,

according to. the size or character of the stalks on which the machine is working. A sprocket belt 28 passes over a sprocket 30,- (see Fig. 2) mounted on a spindle 30", and

;a crank 31 is provided forrevolving this spindle and the sprocket wheels and moving the rods 27 in. or out to change the position A carrier frame 29 rolls 27 aiicl 15 and an elevator 30 operates within said frame and is adapted to receive ears of corn from the roll 27. The lower portion of this elevator operates at an incline parallel, substantially, with the rolls and .the upper portion is elevated at a sharper angle to convey the ears to husking devices, which I have not-thought" necessary to illustrate in this application, as they form no part of my present invention.

At the forward portion of the machine are gathering plates 31 with a space between them, and gathering belts 32 having fingers 33 thereon are mounted tovoperate beneath said plates, said fingers projecting into the space between them, as usual 1n machines of this type. The gathering belts are driven through shafts 34 and 35 having is located near the I driving connections with a shaft 36. Beneath the gathering plates 31 are plates 37 slidably mounted in shoes 38 and yieldingly held toward one another by springs 39. These springs press the plates 37 into a position where they will gather up the cars which are low down on the stalks or those which may be hanging close to the round, and direct them with their stalks in between the rolls'8 and i5, the upper ortions of the stalks being carried forward y the gathering fingers 33. The move ment of the large roll, rotating toward the roll 27 will cooperate with the corrugations 28 to snap the ears from the stalks, and this movement of the upper rolls in the same direction will prevent the cars from being drawn down between them and crushed, and

will also prevent cloggin of the rolls. Durin this operation of t e upper rolls the r0 1 15 cooperating with theroll 8 will grip the stalk and exert a downward pull thereon and aid in separating the ears therefrom. The roll 27, rotating at a much faster speed than the roll 8, will throw the ears as they are snapped 011' the stalks on to the moving carrier 30, on which they are carried to the rear of the machine. I have found with the rolls arranged and operated in this way, that the cars will be rapidly stripped from the stalks and thrown upon the carrier without danger of crushing, which fre quently occurs where the rolls rotate toward one. another, and also without danger of clogging the rolls or the machine.

I have shown a comparatively large, low speed roll rotating toward the snapping roll and cooperating with the roll beneath the sna ping roll to grip the stalks-and exert a ownward pull thereon. I do not wish to be confined to this construction, as obviously some other means may be employed to cooperate with the roll 15 than the low speed roll andstill be within the scope of my invention.

I claim as my invention 1. The combination, with a gathering mechanism, of two rolls between which the corn stalks are fed, one of said rolls rotating at a comparatively low speed, the other roll rotating, at a eater angular velocity and in the same dlrection as said first named roll, and means located below said high speed roll betweenwhich and said low speed roll the stalks are gripped.

2. The combination, with a gathering mechanism, of two rolls between which the corn stalks are fed, one of said rolls rotating at a comparatively low speed and the other roll rotating at a greater angular velocity and in the same direction as said first named roll, said high speed roll operating to snap the ears of corn from the stalks between said rolls.

3. The combination, with a gathering mechanism, of two rolls having cooperating peripheral surfaces rotating in the same direction between which the stalks are fed, one of said rolls being smaller than the other roll and operating to snap the ears from the stalks, and a third roll located beneath the smaller roll and cooperating with the larger roll to hold the stalks during the snapping operation.

4. The combination, with a gathering mechanism, of a comparatively large roll rotating at a comparatively low' speed, a smaller roll contiguous thereto and rotating at a greater angular velocity and having a corrugated surface and operating to engage the ears and sna them from the stalks, and a roll disposed eneath said snapping roll and having means cooperating with said large roll to engage and draw the stalk means, of rolls between which the corn stalks arefed, a carrier arranged near said rolls, two of said rolls having their upper portions rotating toward said carrier at different angular velocity, the higher speed roll operating tosnap the cars from the stalks and throw them upon said carrier, and means below said higher (speed roll cooperating with said lower spee roll for gripping the stalks during the snapping operation.

6. The combination, with a gathering means, of rolls between which the corn stalks are fed, two of said rolls rotating in the same direction and one at 'a greater angular velocity than the other and operating. to snap the cars from the stalks, and a roll disposed beneath said snapping roll and having yieldingly mounted bearings and cooperating with said lower speed roll to grip the stalks and pull them downwardly during the ear snapping operation.

'7. The combination, with a gathering mechanism, of rolls, operating at difl'erent an lar velocity, between which the corn sta ks are fed, said rolls being arranged sidev by side and rotating in the same direction, one of said rolls having movable bearings, and means for adjusting said bearings to increase or decrease the distance between said rolls.

8. The combination, with a gathering mechanism, of two rolls between which the corn stalks are fed, one of said rolls rotating at acomparatively low speed and the other roll rotating at a greater angular velocity and in the same direction as said first named roll and provided with peripheral recesses.

9. The combination, with a gathering mechanism, of rolls arranged side by side between which the corn stalks are fed, said roll rotating in the same direction, but at di erent angular velocity, a carrier arranged adjacent to said rolls, the rotation of the r011 next to said carrier being faster than the other roll and operating to direct the ears from between said rolls to said carrier.

10. The combination, with a gathering 5 mechanism, of rolls between which the corn stalks are fed, said rolls being arranged side by side and rotating in the same direction to snap the ears from the stalks between them, a carrier device provided at one side 10 of said rolls and whereto the ears are delivered, the roll adjacent to said carrier device operating at a difierent angular velocity than the other r011.

In witness whereof, I have hereunto set my hand this 13th day of February 1912. HENRY RUST.
